A more thorough explanation:

Definition: In arbitrio alieno (in ahr-bi-tree-oh ay-lee-ee-noh or al-ee-). [Law Latin] According to the judgment of another. This term refers to property bequeathed to a trustee for the benefit of others, to be used in the trustee's discretion.

Example: John's father left him a trust fund to be used for his education "in arbitrio alieno." This means that John's trustee has the power to decide how much money to spend on his education and what expenses to cover.

Explanation: The example illustrates how the term "in arbitrio alieno" is used in a legal context. When property is bequeathed to a trustee for the benefit of others, the trustee has the power to make decisions about how to use the property. This can include deciding how much money to spend, what expenses to cover, and when to distribute the property to the beneficiaries. The trustee is expected to use their judgment and act in the best interests of the beneficiaries.
